Welcome, Look this over please and tell me if it looks iike your thermostat or not does not show a battery, but look for one anyway.. tell me if you find one, but do not remove it just yet. Pry the front of the thermostat off and tell me if you see an R terminal and a C terminal, if so, use a multimeter to check for 24volts ac between those two. We can go from there.
